BULLETIN BOARD.

To all whom it may concern.'

Be it known that I, ISAAC S. PARKEY, a citizen of the United States, residing at Pennington Gap, in the county of Lee and State of Virginia, have invented a new and useful Bulletin-Board, of which the following is a specication.

This invention relates to bulletin boards and its object is to provide a device of this character having separately shiftable devices mounted at the back thereof and each of which has data arranged thereon and any part of which can be brought into position to be viewed from the front of the bulletin board and read in connection with certain data indicated upon the front of the board.

Another object is to provide means where by the operator at the back of the board can readily determine when the desired data has been brought into position to be seen from the front.

With these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure l is a front elevation of a bulletin board embodying the present improvements. Fig. 2 is a rear elevation thereof. Fig. 3 is a section on line A-B Fig. 2.

Referring to the figures by characters of reference, l designates a frame of any suitable proportions and the front of which is closed by a plate 2 or other suitable device having openings 3 therein, each opening being located between guide cleats 4, which are formed upon the back of the frame l. Channels 5 are produced between these cleats and within each channel is mounted a slide 6 having a spring-pressed dog 7 thereon, designed to engage with any one of a series of teeth 8, formed Vupon one of the longitudinal walls of the channel in which the slide is mounted. As shown in Fig. 2 the walls of each channel lap the slide contained within the channel, and thus prevent said slide from becoming displaced except in a longitudinal direction. When the bulletin board is placed on end however, the slides are prevented from moving downwardly under normal conditions by the catches 7 which engage the teeth 8.

Specification of Letters Patent.

Application filed J'une 25, 1909.

Patented Aug. 30, 1910. Serial No. 504,331.

The front faces of the slides 6 are visible through the openings 3 and each of the slides is provided upon its outer or front face with data designed to be read in connection with data printed above the openings 3 or otherwise indicated on the plate 2. F or example, and as shown in the drawings, the word Train is placed above one of the openings 3, and the front face of the slide appearing through said opening is provided with a column of data giving the numbers of the trains and the directions in which they are traveling. A similar arrangement of data is placed upon one of the cleats 4 adjoining the channel in which said Slide is mounted, the arrangement of this data however being opposite to the arrangement upon the slide, so that when, for example, the data No 23 south-bound appears within one of the openings 3, the catch 7 upon the slide on which this data is indicated, will engage a tooth 8 directly opposite a corresponding item on the adjoining cleat 4. If desired one of the other slides may be provided with numerals indicating hours, and another slide may be provided with numerals indicating minutes, while a fourth slide may have various information printed or otherwise indicated thereon. In each instance the data is reproduced on the adjoining cleat 4, although in a reverse arrangement. Obviously, by` standing back of the bulletin board and shifting the catch 7 so as to register with any desired data, the corresponding data will appear within the openings 3.

A bulletin board such as herein described can be used for various purposes and in the drawings has been shown used as a means for indicating the movement of trains. The device however can also be employed in stores, and in fact wherever it is desirable to use changeable data in connection with permanent headings.

It is of course to be understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention.

What is claimed is z- A bulletin board having a transversely eX- tending slot therein, guide cleats secured upon the back of the board and intersecting the slot, said cleats forming parallel channels therebetween, there being teeth upon one wall of each channel an elongated slide Within the Channel, the Walls of the channels lapping the slide, and a combined Catch and indicator upon each slide for engaging the adj oinng teeth, there being data upon that face of the slide exposed through 1 o posed Within the slot, in which the slide appears, Said eoinhined catch and indicator being located on the rear of the slide opposite the data.

In testimony that I Claim the foregoing as my own, I have hereto afhxed my signature 15 in the presence of two witnesses.
